LuckeyD (and all) thank you for the help on this - does anyone know which components of the A5 board make up S14? Does anyone have any schematics of this board specifically? I have rebuilt boards before, just not A5 and this board looks great. Burn marks make repairs easy to find! Note: I...

Update: Confirmed power at S1, 2, 4, 6 and 8, note - no wires connected to 2 or 6. Confirmed power at S1 pole 3. Confirmed when S1 in 'start' position, B+ at A5-19. No, B+ from A5-18 when S1 in 'start' position. K15 Relay DOES click over when S1 moved to 'start' position. K21 Relay does 'lock'...

Guyfang - [Before you get too far along. Have you troubleshot the S1?] Yes, pole 7 is hot and all other poles are hot in the correct S1 positions, S1 tested good when I was going through the TM. LuckeyD - Thank you for the info, I will go through this and get back with you this weekend! I know...

I have an 804a Genset, 164 hrs. on the clock. New to me (2006 make); here is the run down and trouble shooting to date. 1) Fresh batteries, when using the dead crank switch (on side of engine compartment), engine cranks totally fine, no issues. 2) When S1 (Master Switch) is turned to start, you...

Good morning all, What was the ultimate outcome of this? I have an 804a, identical issues. I have cleaned the MPU, but again, the MPU does not stop the unit from CRANKING at all. I jumped 18-19 on the Governor Control Unit (GCU), and the unit fires right up. Per the Troubleshooting procedure...

Before you go down the road of replacing the AVR, have you pulled the excitation box (I think A30 in the TM) and opened it? The AVR from the original set has 9 or so garbage diodes. I have worked on these exact units (some of the guys on here have helped) and all that it needed was $6-$7 worth...

In the diagram sent by GUFANG, you should remove the cover plate 53 on the side of the pump. The fuel shut off rack is stuck shut and if the plungers under the injector ports were stuck, then the cam likely damaged them. Do not remove the injection pump, since then you will have to retime the...

Pictures of my work in progress and final. Video:

All fixed - runs great now. I have attached the final wire diagram, design worked as presented previously, I filled it out with more details as I finalized the install. THIS SW-200B DIAGRAM WORKS - I am pretty confident the other one will not work (not trying to disregard someone's hard work...

Photos of the S9 switch at various stages for added documentation and review. (I know how hard it is to read and not see this type of stuff).

Alright, here is what I think will work. Does anyone mind checking this over? Would prefer to avoid blowing this thing sky high. Please let me know what you all think - 1) Requires a terminal block (TB1) to replace the terminal connections on the empty T15 and T16 from the S9 switch. 2) Requires...

Existing OEM wire diagram for S-9 overspeed switch. Notice the empty terminals: T1, T3, T6 If we look at that, along with the wire diagram on the side of the s9 switch; it tells me: Relay #1: needs com., NC, and NO - SW200 is missing the NC terminal posts. Relay #2: needs com., NO - nothing...

Here is where I stand on organizing all the existing switch information. 1) the S9 switch identifies each termination purpose - it does NOT identify the purpose of the internal secondary relay block that exist outside the top of the control board - I am not sure what it is tripping at the...

Hopefully your friend is okay. I have spent these past couple weeks reverse engineering this S9 switch. Lots of data coming asap.

Touching base - I'm still holding the phone! Thank you
